Hi! I am discovering the world of STM32 and currently using a STM32F4 to establish a UART communication (send and receive data). I wrote a pretty basic program to send and receive a message (basically a loop) with a baud rate of 9600. The users manua...
Using an F411, I'm having trouble getting the RTC_AF1 (PC13) pin to trigger while powered only by the VBAT pin. The pin seems to drive correctly when VDD is active (tried both Wakeup and Alarm A), but removing VDD does not have the same effect. Is th...
HiI am trying to test STM32H747I-EVAL and LCDMy questions are as belowsAre STM32H747I-EVAL and LCD connected with RGB Connector? ( I want to connect each other with RGB connector when I design a circuits for STM32H747 with LCD) I ...
I'm considering using STLINK-V3MODS for RS-485 via VCP. For it I would need DE (Driver Enable) functionality. (Something similar was commented in an old question)In the user manual, when UART bridge is described it says:"UART signals with hardware fl...
Posted on September 18, 2017 at 16:07I see that this has been asked a few times with no real resolution or workaround, so I'll ask again please?I have USART3 configured at 9600 Baud. I test this with a terminal program also set at 9600 and it works ...
I connect my I2C but when I connect an oscilloscope I have nothing on the clock signal. So probably I misconfigured my clock. Could you give me the information? Thanks in advance. In this picture below I've a warning, do you know how to remove this w...
STM32H750IBK6 REV V sample what is max FMC CLK we can run SDRAMthe datasheet says 2 different values for rev V and REV Y IC revision what is safe area of operating FMC CLK with SDRAM
I wanted to see if the bno055 sensor is ready and set the PB8, PB9 pins as SDA, SCL. (my mcu = stm32f334r8)connectionsSDA_pin -> SDA pin sensorSCL_pin -> SCL pin sensorVCC -> VCCGND -> GNDbut the variable is never HAL_OKthanks for answer.
Can the analog watchdog outputs(ADCy_AWDx_OUT) be attached to the STM32L412’s I/O pins?
I tried download STM32Cubemx and IDE from the ST homepage.However I could not download any program. I could see the message 'not available' only.Is there any problem with my account? (My colleuge could download as usual)
